  1. Heres a fun thread for those to show off their widest and fattest looking megalodon teeth fossils in thier collections. I'll set the tone with the widest fat boy in my collection, I don't have digital calipers but it measure roughly 5.4 inches wide by 6.1 inches long. When I close my hand together it looks even more monstrous. Share yours and join the wide boyclub Got the idea while thinking about what the widest megalodon tooth ever found measures, if anyone does know do share in this thread!
  2. A 2nd look

    Fossils with questions are tossed in a special bucket for thinking about when hunting opportunities start drying up. That time has come. Here a couple: The question: Mastodon or Gomph; I have found Gomph fragments in this location. Another 2 inch fossil, that I almost threw away!! Laying in the sieve, I thought it was unidentifiable bone, but then noted the odd ends. So Bone or Tooth .... If you decided tooth for this 2nd one, you might check out the fossils in this old thread!!! Thanks for all responses.
  3. Help w/ ID new fossil finds!

    Hello! I'm a pretty novice fossil hunter, so I look for things that stand out! Recently I found these in a span of about two weeks, I haven't seen anything like them before. The small ones all have a flat/facet on the posterior side, same teardrop shape, and the larger ones look like " big ears" to me, lol. I thought maybe iron concecretions at first, but the small ones look different, in that they are not "round". Ammonites? Reminds me of some of the pics posted of plesiosaur fossils, I have more pics, but the files are too big to post all at one time - I would really appreciate any insight! Fossil pic 3.pdf
  4. Took this photo of an unnamed eschrichtiid from the Pliocene San Diego Formation of San Diego County in March 2019. Until the 2000s, the fossil record of gray whales was confined to the Pleistocene, but thanks to the work of Michelangelo Bisconti, it is apparent that gray whales emerged about the same time as the oldest rorquals (Eschrichtioides was long considered a balaenopterid, but eventually recognized as a gray whale relative).
  5. The balaenid specimen SDNHM 43880 I photographed at the San Diego Natural History Museum in December 2017 was once referred to Balaenula, but Churchill et al. (2012) recovered it as sister to the bowhead whale rather the right whales and Balaenula, and recent erection of Archaeobalaena dosanko for the one balaenid specimen from Japan previously referred to Balaenula makes clear that the previous referral of SDNHM 43880 was untenable. However, it is unclear whether SDNHM 43880 is a new genus and species or alternatively a new Balaena species due to the cladistic position of SDNHM 43880 obtained by Churchill et al. (2012). Churchill, M., Berta, A. and Deméré, T. (2012), The systematics of right whales (Mysticeti: Balaenidae). Marine Mammal Science, 28: 497-521. doi:10.1111/j.1748-7692.2011.00504.x

  7. Hi all - in the hopes of attempting to reach a wider audience, and anyone who has collected possible sea otter fossils, I'm sharing the first two posts from my blog "The Coastal Paleontologist" in a short series on sea otter paleontology and evolution. The first one is mostly a bit on sea otter biology, and the second is the first one that really deals with the paleontology aspect. The third (and fourth?) posts will deal with what the limited fossil record can tell us about sea otter evolution. The sea otter fossil record is quite poor, and I'm hoping that some of you may have found some fossil specimens and might consider making them available for scientific study. Anyway, here's part 1: https://coastalpaleo.blogspot.com/2020/05/the-terrible-fossil-record-of-sea.html And part 2: http://coastalpaleo.blogspot.com/2020/06/the-terrible-fossil-record-of-sea.html Part 3: will update as soon as I get it finished! And a teaser - the left mandible of the holotype specimen of Enhydra macrodonta from the Crannell Junction locality right off of Highway 101 near Arcata, California. I spent about 3 years emailing various curators about this fossil, if they had it on loan, and I finally got a response from Dr. William Miller III at Humboldt State University in Arcata that he didn't remember such a specimen existing there. The paleontologist who named it, Dr. Frank Kilmer, who was retired, mailed me a letter indicating that the mandibles had been given back to the private collector (!!!) after the species was published - but nobody at HSU knew their name! One former student did, but would not return my phone calls. I visited HSU in 2008 when I was an undergraduate student and rifled through their teaching collection and found A mandible, but I didn't think it was THE mandible, because of Kilmer's letter, and a misplaced label suggesting it was from a different locality (and therefore a duplicate specimen rather than the original). Dr. Miller indicated I should arrange for the fossils to be transferred to a larger museum, as he was certain that the collection would be thrown in the garbage after he retired! I visited again two years later and set aside all the specimens that should be transferred and secured an agreement from HSU for the material to be transferred to UC Berkeley, which finally happened about five years later. I did not realize that this mandible was in fact THE mandible, or at least half of the holotype (the right mandible is still missing, presumably in that private collection) until I was able to download a much, much higher quality scan of the photographic plates in Kilmer's 1972 paper, and I was able to match barnacle scars between the published image and the fossil. So, we may not have the more complete of the two mandibles, but at least we have one of them, and it is my hope that there is more material in private collections and that more can be discovered in the future.
  8. Strange bone from Russia

    This bone was found on Azov See shore, Russia. Probable geological age is late Neogene (Miocene or Pliocene). I don't know what this thing is: metacarpal, metatarsal or calcaneus? What a strange hooked process on the proximal epiphysis that is not characteristic of the metapodium? I'd like to get your opinion.
  9. Carcharodon carcharias

    From the album Misc. Cenozoic Specimens

    Carcharodon carcharias.
  10. Carcharodon aff. hubbelli

    From the album Misc. Cenozoic Specimens

    This is most likely a worn Carcharodon carcharias.
  11. EOS small treasures

    Beautiful day Friday. Sun was shining. Besides sprinkles, rain held off until late afternoon. I am finding interesting fossils. Let me try 2. I have seen similar previously, but never identified. Maybe others have, Then a tooth: Have there been occurrences of Aulophyster like small teeth on the east coast of the US? @Boesse Like I implied, interesting fossils.
  12. Purse State Park Trip

    Took a trip to purse state park today, got there around 9:30 and the lot was already pretty full. Made our way down the beach to the spots we like to search and my wife found the biggest croc tooth we have found, at least double the size of any of the other ones we have found. A little bit later walking along the low tide shoreline I did a double take and saw the big Otodus tooth pictured. We were able to find a lot of other nice size otodus and sand tiger teeth during our time there. On our way back walking the beach entrance and Wades Bay were packed with at least 100 people and their boats. Overall a great day for hunting!

  24. Nanjemoy Trip 5/7/20

    First official post! Drove to Nanjemoy with my wife to shark tooth hunt for the day. Wewere the only people there when we arrived, usually it can be pretty packed with cars. Usually we find a lot of smaller teeth and a somewhat longer sand tigers. We found two of the otodus up at the high tide line within 15 minutes of each other after walking down the beach and were both really shocked and excited. Decided to stop and eat lunch and that’s when I found the biggest and by far the biggest we have ever found and in such great condition. Only the tip of the tooth was sticking out when I spotted it.
  25. fish or reptilian?

    Hi to everyone again!, I have found these teeth in coastal sediments Pliocene in age. Do they look like fish teeth or reptilian? Can't identify any of these four. Thanks!
